The present invention relates to improvements in suspension means for a cooling unit, and its particular object is to provide a suspension means of the character described which is simple in construction and greatly facilitates the act of` large rooms used for storing of meats, vegetables,

fruits, or any generally perishable foods. Cooling units of this type are usually of considerable dimensions and of heavy weight, and the act of suspending th'e same from the ceiling of the walkin box under present methods is an awkward' task and requires the cooperation of several attendants, the ceiling usually being above mans height.

In the present invention it is proposed to provide a suspension means which greatlyv simplifies the operation of suspending the cooling unit and which' allows one man to perform the operation in normal installations It is further proposed to provide a suspension means of the character described which allows the fastening of the unit in position to be performed from the outside of the unit, so that th'e latter may be completely assembled before installation.

And nally it is proposed sion means for the unit that is particularly adapted to firmly anchor the unit tothe ceiling, without any chance of any parts working loose.

Further objects and advantages of myv invention will appear as the specication proceeds and the novel features f my means for suspending a cooling unit from a ceiling or the like Will be fully defined in the claims hereto appended.

The preferred form of my invention is illustrated in the accompanying drawing, forming part of this application, in which:

Figure 1 shows, in side elevation, two cooperative members, adapted for fastening to the ceiling and th'e unit respectively, in an intermediate position of the installing operation;

Figure 2, a Vertical section through an installed unit;

Figure 3, a bottom plan View of the two members in Iassembled relation; and

Figure 4, an end view of the two members.

While I have shown only the preferred form of my invention, I wish to have it understood that various changes or modifications may be made within the scope of the claims hereto attached without departing from the spirit of the invention.

to provide a suspen- 6 Claims. (Cl. 248-311) Referring to the drawing in detail, the cooling unit I may be of any conventional construction, is square in horizontal cross-section, andcornprises in its general features an open box `structure comprising four angular corner-pecesarranged in th'e four corners of the box, a drip pan 3 joining the corner pieces near or at the bottom and a top plate 4 joining the corner pieces at their upper ends by any suitable means.

The unit thus presents a square box with large openings 5 in the four sides thereof.

A conventional coil 6 is provided inside the box for carrying a refrigerant, and winds in a number of turns along the walls of the box, certain sections of the coil being exposed along the box openings While other sections are hidden behind the corner pieces. The exposed portions are preferably made of conventional brush type construction to present large radiating surfaces.

The drip pan 3 h'as a central opening 'I in which is mounted a conventional fan 8 drivenby the motor 9 supported in the box in any suitable manner.

The top plate Il, which stretches across the top of the box, has two depending flanges or rails IU and II which project downwardly, in the planes of the side walls, to within fairly close proximity of the coil sections.

This top plate d with its flanges serves as part of a suspension means, and is made for cooperation with a second plate I2 attached to th'e ceiling as indicated at I3.

The plate I2 has two depending flanges I4 and 5 5 and is slightly longer than the plate II, so as to allow the plate 4 with its flanges to nest in the plate I2 with its flanges, with' the flanges in frictional contact.

The nange I4 of the ceiling plate is formed with an inwardly projecting ledge I5, and the latter has a toe I 6 rising from its inner edge.

The width of the flange Ii] on plate 4 is such that the ange I0 ts between the plate I2 and the ledge I5. 'I'he flange II of plate 4 is formed with a ledge I 'I and a toe I 8 similar to those of the flange I4.

All of the flanges are preferably formed with suitable registering bolt holes I9, and may be secured upon one another by bolts and nuts in a conventional manner.

The manner of using my invention will be readily understood from the foregoing description.

In order to install the unit, the operator merely raises the unit toward the ceiling in tilted position, as in Figure 1, hooks the flange I0 over the toe I6 to come to rest on the ledge I5', and then swings the other end up for the flange l l to bear against the inside of flange i9.

Possibly friction will hold the unit in place ternporarily, or the opera-tor may place a nail or bolt through two corresponding holes I9 for temporarily holding the unit. He may then proceed to permanently fasten the flanges upon one another, as by bolting or riveting or Welding.

It will be noted that my method of installation is rendered Very simple in this manner and may be readily carried out by one person who is strong enough to lift the unit.

I claim:

1. Means for suspending a cooling unit from a ceiling comprising a member adapted for securing to the ceiling and having a pair of downwardly projecting flanges, with a ledge on one of the flanges, and a pair of Vertical rails on the cooling unit spaced to fit between the flanges in face-to-face relation therewith, whereby the cooling unit may be raised in tilted position for engagement of one of the rails over the ledge and may then be swung into horizontal position for bringing both rails into face-to-face relation with the flanges.

2. Means for suspending a cooling unit from a ceiling comprising a member adapted for securing to the ceiling and having a pair of downwardly projecting flanges, with a ledge on one of the flanges, and a pair of vertical rails on the cooling unit spaced to fit between the flanges in face-to-face relation therewith, whereby the cooling unit may be raised in tilted position for engagement of one of the rails over the ledge and may then be swung into horizontal position for bringing the rails into face-toface relation with the flanges, the ledge having a toe along the inner edge to prevent slipping off the rail over the front edge of the ange during the assembling operation.

' 3. Means for suspending a cooling unit from a ceiling comprising a member adapted for securing to the ceiling and having a pair of downwardly projecting flanges, with a ledge on one of the flanges, and a pair of vertical rails on the cooling unit spaced to fit between the flanges in face-to-face relation therewith, whereby the cooling unit may be raised in tilted position for engagement of one of the rails over the ledge and may then be swung into horizontal position for bringing the rails into facetoface relation with the flanges, the flanges and the rails on the ledge side being of substantially the same depth and of a length greatly in excess of their depth to preclude lateral tilting and slipping of the cooling unit during the installing operation.

4. Means for suspending a cooling unit from a ceiling comprising a pair of flanges projecting downwardly from the ceiling, with a ledge on one of the flanges, and a pair of vertical rails on the cooling unit spaced to fit between the flanges in face-to-face relation therewith, whereby the cooling unit may be raised in tilted position for engagement of one of the rails over the ledge, and may then be swung into horizontal position for bringing both rails into face-toface relation with the flanges.

5.
